Synopsis
========
An input validation flaw in Samba may allow a remote attacker to cause
a Denial of Service by excessive consumption of CPU cycles.
Background
==========
Samba is a freely available SMB/CIFS implementation which allows
seamless interoperability of file and print services to other SMB/CIFS
clients.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-fs/samba < 3.0.8 >= 3.0.8
< 3.0
Description
===========
An input validation flaw exists in ms_fnmatch.c when matching filenames
that contain wildcards.
Impact
======
A remote attacker may be able to cause an abnormal consumption of CPU
resources, resulting in slower performance of the server or even a
Denial of Service.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Samba users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.8"
